This issue is not related to the kernel,
for btrfs-progs v4.15.1 on Bionic, the btrfs send / receive command should be:
* btrfs send [-ve] [-p <parent>] [-c <clone-src>] [-f <outfile>] <subvol>
[<subvol>...]
* btrfs receive [options] <mount>
So the btrfs send in the script should be changed from:
btrfs send $MNT/snap1 -f $TMP/base.send
To:
btrfs send -f $TMP/base.send $MNT/snap1
For receive, it should be changed from:
btrfs receive $MNT -f $TMP/base.send
To:
btrfs receive -f $TMP/base.send $MNT
This change should be tested across distros, otherwise we need to use different
command layout for different version of btrfstools.
** Summary changed:
- 29d6d30f5c8aa58b04f40a58442df3bcaae5a1d5 in btrfs_kernel_fixes failed on B
+ btrfs send / receive command with -f argument position in btrfs_kernel_fixes
is causing failures on B
** Changed in: linux (Ubuntu)

fix 29d6d30f5c8aa58b04f40a58442df3bcaae5a1d5
Btrfs: send, don't send rmdir for same target multiple times
When doing an incremental send, if we delete a directory that has N > 1
hardlinks for the same file and that file has the highest inode number
inside the directory contents, an incremental send would send N times an
rmdir operation against the directory. This made the btrfs receive command
fail on the second rmdir instruction, as the target directory didn't exist
anymore.

Receive subvolumes from a stream
Receives one or more subvolumes that were previously
sent with btrfs send. The received subvolumes are stored
into MOUNT.
The receive will fail in case the receiving subvolume
already exists. It will also fail in case a previously
received subvolume has been changed after it was received.
After receiving a subvolume, it is immediately set to
read-only.
-v increase verbosity about performed actions
-f FILE read the stream from FILE instead of stdin
-e terminate after receiving an <end cmd> marker in the
stream.
Without this option the receiver side terminates only in
case
of an error on end of file.
-C|--chroot confine the process to <mount> using chroot
-E|--max-errors NERR
terminate as soon as NERR errors occur while
stream processing commands from the stream.
Default value is 1. A value of 0 means no limit.
-m ROOTMOUNT the root mount point of the destination filesystem.
If /proc is not accessible, use this to tell us where
this file system is mounted.
--dump dump stream metadata, one line per operation,
does not require the MOUNT parameter
